Thanks for the reply. How do I verify where the sources should be after the rpm install? How do I install only the headers, since that phrase keeps popping up but like many things on the net, no one ever actually verifies the process for making sure you have them installed, nor how to do it in the first place? Here is the listing of kernel release and available rpms where I downloaded them. [sysadmin@comcserver1 tmp]$ uname -r 2.6.18-194.el5 [sysadmin@comcserver1 tmp]$ ls |grep kernel |grep 2.6.18-194.el kernel-2.6.18-194.el5.src.rpm Looks like I am going to have to crack open these linux kernel books I have been putting off, now. :P -- Respectfully, Martes G Wigglesworth M.
